Application filed September 2, 1913. Serial No. 787,670.

.T all whom it mag concern -Be it known that I, JEAN on BLoNAY, a

citizen of the Republic of Switzerland, re 'siding at Lausanne,Switzerland, have iii-- vented new .and useful Improvements in Packingand'Wrapping Machines; and I do hereby declarethe following' to. be afull,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters or figures of reference marked thereon, which forma partof this specification.

This invention relates to a machine for piling circular, disk likebodies and for wrapping up these piles of disks inat least one envelop.In machines of. this kinda number of disks are piled up in a receptacleand the pile is then fed in a wrapping device, in which an envelop iswrapped around the pile by means of rollers, while the parts of theenvelop projecting beyond the, front end of the pile are folded over thelatter. These machines are particularly adapted for packing rolls ofchocolate disks, the pile of disks being provided at first at each'ofitsendswith a closing disk and afterwardwrapped up in an inner and in anouter envelop (label) projecting beyond said closing disks, the outerenvelop or label being also fastened by' means of gluten to the roll andto theclosing disks.

' A convenient mode of carrying this inven tion into effect is shown byway of example in the accompanying drawings, in wh'ich Figure 1 is anelevation of the machine seen from the side of the wrapping device, apart of the driving mechanism being shown in'section, Fig. 2 is anelevation of the machine seen from the side of the feed mechanism forthe envelops, showing a part of the driving mechanism in front view,

The machine illustrated in the accompanying drawings is provided with a.feed device for the chocolate disks and a device for piling these disks;it is further provided with means for providing the piles of disks attheir two ends with closing disks of cardboard. The machine is alsoprovided with meansfor conveyingthe piles of disks to- The machinepossesses further a wrapping device for wrapping up the pile of disksinto an' inner and an outer envelop, said devicebeing-provided with feedmeans for these envelops. These latter means consist of a feed devicefor the inner envelops of cardboard, this device being provided withscis- Patented Apr. 20, 1915.

sors for cutting the strips from a band, and of a feed device for theouter envelopsconsisting of thin paper sheets (labels), the latterdevice being also provided with means for applying the gluten and withan air" permits an inspection of those parts of the driving .devicewhich are arranged inside the a frame. This device actuates all themovable worm engages a worm wheel 13 mounted on a vertical shaft 14supported in the frame 1. The worm 12 and the worm wheel 13 are'arrangedin a closed casing 15. The shaft 14 drives by means of two toothedwheels 16, 17 a shaft 18 carrying a cam drum 19, provided at itscircumference with a numberof lifting cams. A' lifting cam 20 actuatesthe scissors, a lifting cam 21 actuates the devicefor introducing apile-of disks into the -wrapping device and for pushing the finishedchocolate rolls; out of this device, a further lifting cam 22 actuatesthe air pump of the feed device for the labels, while a lifting cam 23actuates the device for piling up the chocolate disks. (Fig. 3).

On the shaft 18 is mounted a toothed wheel 24, provided on itscircumference with a toothless part and on the to of the latter with alocking member 25. Fig. 8). The wheel 24 engages a toothed Wheel 26carrying a ring 2 provided with a recess 28 corresponding to the lockinmember 25 attached to the wheel 24. 'l he toothed wheel 26 is fixed to asleeve 31 (Fig. 8) on which are also mounted a toothed wheel 29 and achain-wheel 30 (Fig. 3), said sleeve 31 being loosely mounted onto theshaft 14. The chain wheel 30 transmits the drive to the feed rolls thetoothed wheel 37, that the parts 29, 32,

33 and 37 are rotated as soon as the wheels 24 and 26 are brought intogear, while said parts remain stationary when the parts 25 and 28 arebrought into engagement.

The intermittingly rotating shaft 33 actuates the device for feeding thechocolate disks, and for piling up the latter and also the wrappingrolls of the wrapping device. T0 effect this, there is provided a chainwheel 34 fixed to the shaft 33, said Wheel 34 being connected by meansof a chain 35 to a chain wheel 36, loosely mounted onto'the shaft 18 andconnected to a toothed wheel 37 (Fig. 3).

The continually rotating shaft 18 carries a wheel 38 provided with teeth39 (Fig. 6). This wheel carries a ring 40 having a recess 41. The ring40 works together with a ring 43 provided with a number of recesses 42and attached to .a toothed :wheel'44, which may gear with the teethflofthe wheel 38. The wheel 44 is connected by means of a sleeve 45 (Fig. 7)to a toothed Wheel 46;

this sleeve with the two toothed wheels being loosely mounted onto theshaft 14. The

toothed wheel 46 gears with a pinion 47 carried by the plate 2 and thepinion, 47 gears with a toothed wheel 48, connected with the table 49arranged above the plate 2. The wheel 48 is fixed to the hub of thetable 49, the hub being loosely mounted onto the shaft 18 and beingsupported in the plate 2.

(Figs. 3 and 7). The toothed wheel 46 also gears with a pinion 50 fixedto a vertical shaft 51 arranged in the frame 1. The shaft carries also apinion 52 gearing with a toothed wheel 53, which is mounted on thevertical shaft 54 driving the feed'device for the labels (Fig. 2). Thepinion 52 is connected to a chain wheel 55 actuating the device forapplying the adhesive substance or gluten (Figs. 2, 6 and 7).

The Wheels 38 and 44 form together with the locking parts 40 and 43 afeed device which imparts an intermittent rotary movement to the table49 and the wheels 51 and 54, thewheels 44 and 46 remaining stationary,when the ring 40 enters in a recess 42 provided on the ring 43, whilethe wheels 44 and 46 are=rotated through a certain angle, when the teeth39 on the Wheel 38 gear with the Wheel 44, the table 49 describing eachtime a quarter of a revolution.

2. The dem'ce for feeding the separate chocolate disks into the machineand for piling up these disks, (Figs. 14 and 9- 16.)-The intermittinglyrotating shaft 33 guided in the frame 1 and the plate 2'is'connected bymeans of bevel Wheels to a horizontal shaft 56, carried by brackets 57connected to the plate 2. (Figs. 10 and 11). The shaft 56 actuates bymeans of a chainwheel gearing 58 a screw pinion 59 gearing with a screwwheel 60, said pinion59 being loosely mounted on a shaft 61 parallel tothe shaft 56 and supported by the brackets 57. (Fig. 11). To the screwwheel 60 is connected a roll 62, over which runs an endless conveyingband 63 passing also over a the rotation of the disk 73 with a secondroll 64,. which is carried b a bracket of the machine frame (Fig. 9 Onthe same level with the upper horlzontal part of the band 63 andlaterally of the latter there is provided a fixed table 66 and alongsaid band there are arranged lateral guide rails 67, the one of which isprovided with a bent portion 68 extendin across the band and acting as astop. igs. 4 and 10).

The table 66 is used to take up the round chocolate disks 8, which haveto e piled up. One side of these disks is greater than the opposite one.These disks 8 are taken by hand from the table and then placed' upon theband 63, the side havin the aller diameter lying underneath ig's. 4 and9). The band 63 carries the disks s lying one behind another withinreach of a conveying wheel 69, provided with four conveying arms 70 andfixed on a shaft 56. (Figs. 10 and 11). p

The wheel 69, 70 engages apivotally mounted holder 71 (Figs. 11 and 13)carried by the shaft 61 and provided with a rectangular slot 72 adaptedto take up a single chocolate disk. The shaft 61, and therefore also theholder 71, are moved intermittingly by the shaft 56. To impart such amovement to these parts 61 and 71 there is provided a disk having at itscircumference two sets of teeth, arranged diagonally one oppositeanother (Fig. 12). These sets of teethgear alternately during pinion-(Figs. '11 and 12) ,mounted on the shaft 61, imparting thereby anintermittent motion to said pinion 75 and the shaft 61. The toothedparts 7 4 of the disk 73 have such a length, that just half a revolutionis im-. parted to the pinion 71, and therefore also to the shaft 61,when said parts 74 engage the pinion 73. The holder 71 is brought into ahorizontal position during each pause of the shaft 61, the lower wall ofthe opening 72 being then in the same horizontal plane, 71. e. on alevel with the upper half of the conveying band 63. Figs. 10 and 14-16.)To lock the shaft 61, and the holder 71, when they remain stationary,there are providedon the disk 73 two segment-shaped locking members 76(Fig. 12)

engaging oppositely arranged recesses 77 of a pinion 75 connected to thedisk 78 and working in such a manner together with said recesses, thatthe shaft 61 is not moved as long as the locking members run in therecesses 77. Below the holder 71 there is provided a stationarytrough-like bent guide-plate 79 (Figs. 10 andll) preventing thechocolate disks in the holder 71 from falling out during the rotation ofthis holder 71.

In the table 49 there are arranged four 1 vertical cylindricalreceptacles 80 (Figs.4

and 9) placed toward one another at an :angle of 90 and adapted toreceive the chocolate disks, respectively the finished chocolate rolls.These receptacles are open at their lower and upper ends. (Fig. 3). Inthe plate 2 of the frame 1 there is further guided a vertical rod 81carrying at its upper end a plate 82, which forms alternately the bottomof the four receptacles 80,

' when they are filled with chocolate disks.

This rod 81 is connected by means of a rod 83 to a lever 84 (Fig. 3)pivotally mounted in the frame 1 (Fig. 5) and carrying a roller runnmgin a cam groove 23 of the cam drum 19. The rod 81 passes during thepause of the intermittingly rotating table 49 through the latter and itenters into the receptacle 80 situated immediately above it and itreaches in the latter its uppermost position shown in Fig. 3, whereuponit falls again gradually downward in accordance with the shape of thecam groove 23.

For each receptacle 80 thereis provided beneath the table 49 a pair oflevers 85, 86

(Fig. 4) having several arms. The arms of these levers arranged belowthe receptacles 80 are provided with supporting jaws and they areoperatively connected to other arms, a third arm 85 of the lever 85being acted upon by a spring, which presses said arm against a disk 88provided at its circumference with recesses 87. As hereinafterdescribed, the levers 85, 86 are actuated in such amanner by said disk88 that they are opened before the rod 81 enters in the receptacle 80situated above this rod 81 in order to permit the latter, to passbetween the above mentioned carrying jaws, while they are closed as soonas the rod 81 leaves the receptacle 80, whereby the jaws replace theplate 82. To the two supports 57 are further attached by means of screwstwo receptacles 89, each containing a pile of round disks 7c ofcardboard (Figs. 4.- and 17.) Each of these receptacles has a slottedbottom 90 and an outlet passage 91 for said disks of cardboard. {1(Figs. 17 and 18.) said receptacles 80 is also provided at its upper endwith a projecting nose 92, which pushes the lowermost cardboard-disksout of the receptacle 89.

When a receptacle 80 passes below a receptacle 89 and previously toreaching the position, in which it is opposite the holder 71, it pushesby means of the nose 92 -a disk k out of said receptacle 89, the disk isfalling then into the receptacle 80; as soon as Each of the table andthe receptacle 80 filled with I the uppermost chocolate disk of thepile,

so that there comes to lie a disk k above and below each pile ofchocolate disks. These ,disksk impart to the pile greater rigidity.

, stop 66. The

- intermittent rotary motion to the shaft. 56

and therefore also to the'conveying wheel 69, 70.- This is efiected insuch a manner, that the conveying wheel describes three revolutionsduringthe time that the wheel I 29 gearing with the wheel 24 (Fig. 8)makes one revolution, the wheel 69, being then brought to a stand stillafter each three revolutions. While the conveying wheel is rotated threetimes, its four arms 70 introduce twelve chocolate disks into thereceptacle 8O situated in frontof the holder 71, the chocolate disksbeing alternately turned through an angle of 180 by the intermittinglyrotated holder 71 before they fall into said receptacle 80. Theseproceedings take place in the following manner.

At the beginning of the filling of a receptacle 80 with chocolate disks8, the rod 81 carrying the plate..82 is in its uppermost position (Fig.3) and the plate 82 carries a cardboard-disk h. The parts of the devicecapable of rotating rotate in the direction 01''- the arrows shown inFigs. 10-16. It is now assumed, that the conveying wheel 69, 70 hasalready pushed a disk 8 into the receptacle 80 and that a second disk 8is taken up by the stationary holder 71, while a third disk 8 carried bthe band 63 is in front of the fist disk is now turned before itsintroduction into the receptacle 80, since a toothed part 74 of thewheel '73 engages the inion 75 so that the shaft 61 and the holder 1 areturned through an angle of 180. The smaller side of said disk liestherefore 'upward in the holder 71 (Fig-15) and it is then pushed inthis position into the receptacle 80, as soon as the second disk isintroduced from the conveying band 63 into the holder 71. The lowerlarger side of the first disk introduced into the receptacle lies uponthe cardboard-disk is carried by the plate 82 (Fig. 10). I

As the holder 71 remains now stationary for a certain time, members 7 6engages a recess 77 provided in the disk 78 of the pinion 75, while thewheel 69, 70 is continually rotated, it is evident, that the second diskpushed into the holder 71 will not be turned therein, but remains in theposition, that it had upon the conveying band 63 (see Fig. 10). Thissecond disk is then pushed into the receptacle 80 as soon as a thirddisk '8 is conveyed by the wheel 69, 70 to the holder 71 (this seconddisk is shown in Fig. 10 in dotted lines). The smaller side of thesecond ,disk pushed into the receptacle 80 is then brought into contactsince one of the locking with the correspondin smaller -side'of theprevious] introduced rst disk. The third disk 8 ta en up by the holder71 is again turned owin to a turning movement imparted to thls holderaudit is then pushed into the receptacle 80 as soon as a fourth disk is'introduced into the holder 71 (see position shown in Fig. 15 in'dottedlines), the

larger side of tlllS' third. disk coming then in contact with theupwardly lying larger side of the second disk 8. (Fig. 16). The

holder 71 is now brought to a standstill and the fourth disk 8 taken upby the holder 71 to lie adjacent the smaller upwardly lying side of thethird disk. The above described operations are repeated till thereceptacle is filled with twelve chocolate disks, which lie alternatelywith the one and the other of their corresponding sides of the same di-.ameter one upon another.

While the receptacle 80 is gradually filled with disks,'the cam groove23 acts in such a manner upon the rod 81, that the latter is graduallylowered and is drawn finally out of said receptacle, the levers 85, 86arranged below said receptacle. being then closed, so that the lowerdisk of cardboard h and the pile of disks arranged above the latter arenow supported by the two levers 85, 86.

The table 49 is now again rotated through an angle of 90, acardboard-disk being taken out of the second receptacle 89 during thismovement and put upon the pile of disks. At the same time a newreceptacle 80 is placed opposite the holder 71, said receptacle, afterhaving taken up a disk of cardboard h, being also filled in thehereinbefore described manner with chocolate disks 8. p

3. The device for bringing the piles of disks within each wrappingdevice and for finished chocolate rolls out of the wrapping device,(Figs. 1-4, 6, 7.) This device consists of the hereinbefore describedtable 49 provided with receptacles 80 and levers 85, 86and'intermittingly rotated through'an angle of 90 by the shaft 18, andfeed wheel 38, and of the aforementioned disk 88 actuating the levers85, 86'. This disk 88 is loosely mounted onto the hub of the table 49and it is capable of rotating through a small angle. For this purposethere is provided in said disk .88 a slot 93, into which projects a pin94 provided on the plate 2, the'disk 88 being pressed by atension-spring 95 against said pin 94. (Fig. 4) The disk 88 is connectedconveying the with an arm 93, which is intermittently shaft 14 so that arotary motion is imparted to said d cesses 87 are provided on thecircumference of said disk 88. there are provided three of such recesses87 separated one'from another by an arc. of

90 (Fig. 4) and engaged by the arms 85 of the levers 85 opening andclosing the carrying jaws of the levers 85, 86. Each of these recessesis provided with a steep part 87 and an inclined lifting part 87 99denotes a tube leading away the finished choco late rolls (Fig. 1). Thistube is fixed to the plate 2 and it is open at its'upper end.

When the table with a receptacle 80 is in front of the holder-71, thearm 85 of the corresponding lever pair 85, 86 acted upon by the tensionspring '98, falls over the steep part 87 into said recess so that themarrying jaws are rapidly closed, while the rod 81 and the plate 82carried by the latter are pushed from below into the receptacle 80, inwhich they form a support for the cardboard-disk is introduced into saidre- .iceptacle and supported till now by said jaws. (Fig. 3). After thereceptacle 80 has been filled with chocolate disks and at the timethatthe rod 81 with the plate 82 leaves the receptacle, the revolvingarm 97 .strikes against. the arm 96 providedon the disk 88, so that thelatter is rotated through an angle,the amount'of which depends from thedimensions of the slot 33, in such a direction' that the lever arm 85 israpidly r0- asytated recess 87. This movement of the'disk 88 has theeffect to bring the carr 'ng jaws rapidly below the lower cardboardliisk projecting laterally beyond said plate, so that they act as asupport ,for the pile of disks mediately afterward and before the arm 85has time to engage, after the releasing. of

carrying aws of these levers remain in their 1 closed position. i 1 .Thereceptacle "80 containing the pile of disks is now on the right handsidewith reference to Fig. 4, near the feed device for the labels and itremains there till the following receptacle is.'filled with chocolatedisks without the corresponding levers 85, 86 being operated. Thefollowing intermittent movement of the table 49 ,parries the pile ofdisks within reach oftl ewrapping device, 2'. e. of the members for pushing the pile between the wrapping rolls. The arm 85 of-the lever pair85, 86 falls 6 hereby into the recess 87 of the disk 88, so

isk. .As already stated, several re- In the present instance by theinclined lifting part 87 of the arranged above said cardboard-disk. Im-

.=circumference of the disk 88, so that the that the carrying jaws areopened to.per-- mit to said pushing'members for feeding the f pile tothe wrapping rolls to seize the pile. i

-The table remains then stationary and "the 4 carrying aws remainopen'till the pile of 7 disks is wrapped up and till the wrapped upchocolate roll is conveyed from the wrapping rolls into the receptacle80. The carrying jaws of the levers 85,86 are then again closed by thearm 97 acted upon by the revolving disk 88, as it is the case after thefilling of the receptacle with chocolate disks, so that the finishedchocolate roll. is supported b said jaws. The table is hereafter againrotated through an angle of 90, so that the receptacle is now above thedischarge pipe 99. If the arm -of the lever pair 85, 86 falls now intothe recess provided on the disk 88, the carrying jaws are opened, sothat the chocolate disk may fall 85 from the receptacle 80 into the pipe99 which conveys it into another receptacle. "4. The device for feedingthe pile of disks into the wrapping device and for pus the finishedchocolate rolls out of this de- 9 I vice, (Figs. 1-5 and29.)-This'device has -two shafts 100;and 101 movable inra verticaldirection and arranged one upon an other in the same vertical axis. .Thelower .shaft 100 forms a rack-and it is guided in a fixed part 102 ofthe frame 1 as well as in a part 103 of the lower casing of the wrappingdevice (Fig. -19). This-rod is moved to and fro by means ofa. cam drum19. For this purpose there is movably km I the cam drum 19 (Figs-3, 5and 40). The 1 toothed formation of the slide is engaged by a pinion106,- which is mounted on a shaft, supported in the fixed part- 102 andcarrying a toothed wheel 107 gearing with the rack 100 (Figs. 3, 5'and40.) While no the cam drum 19 is once rotated, the slide is moved onceto and fro and the rod 100 is moved at the same time once up and down bymeans of the toothed wheels 106 and 107.' In the upper end of the rod100 is adjustably arranged a pin 108, acted u on by a spring '109, whichtends to move t e pin outward into the position shown in-Fig. 19. A stopnot shown prevents this pin to move beyond this position. I

The upper pushing rod 101 is loosely guided in a sleeve 110 attached tothe two casings of-the'wrapping device (Figsrl, 4

"bolt 114 projects through a slot 115 rovided in the rod 101 and it isprovide with a tapered head 116 acted upon bya tapered shaft117, whichis capable of being adjusted vertically in the sleeve 110 to displacethe bolt 114. The shaft 117 projects beyond the lower end of the sleeve110. (Figs. 29 and 39). The pin 112 carries-at its lower end a'disk-likemember 118, while the rod 101 roll. The pin 112 is now held in itsproper position by thebolt 114 engaging the groove 113. and the rod 101is supported by the member 118 of the pin 112 (Fig. 37 ),.so that thetable 49 is capable of rotating and of conveying a new receptacle 80containing a pile of disks between the rods 100 and 101.

The lower rod 100 is now moved upward, the pile of disks contained inthe receptacle being also moved in the same direction, so that itimparts 'a short upward movement to the rod 101. Owing to this movementof the rod 101 the tapered shaft 117 is pushed by the flange 119, sothat it acts upon the head 116 of the bolt 114, moving the latterbackward and releasing thereby the pin 112. This pin 112 and the rod 101are now only acted upon by their own weight and they are supported bythe pile ofdisks. The'weight of the two parts 101 and 112 presses nowthe pm 108 of the lower rod 100 into the rod 101 (Fig. 3).. 1 As soon asthis lowerfrod 100] is moved downward, the pile of disks acted upon bythe released parts 101, 112 isalsomoved in the same direction and pushedbetween the wrapping rolls .of

the wrapping device. The taperedrod 117 falls again downward andreleases the bolt 114, which .is again pressed against the pin 112. Thering 111 strikes now against the sleeve 110, so that the rod 101, butnot the pin 112, is prevented from moving farther downward. As soon asthe rod 101 is kept back and its'weight taken off the pile of disks, thepin 108 acted upon-by its spring 109 'is moved during the downward movement of the rod 100 the same amount out of 7 this rod 100 as the pin 112is'moved out of completed, the cam drum 19, respectively its cam groove21, lifts again the lower rod 100 as well as the finished chocolate rolland (Fig. 38.

the parts 101, 112, the pins 108 and 112 be-- ing then moved into theirrods, so that the chocolate roll is held between the shafts or rods 100and 101. As soon as the roll reaches the receptacle 80, the bolt 114engages again the groove 113 of'the pin- 112,

so that the latter and the rod 101 are locked in their. uppermostposition, while the rod 100 is moved below the\table. Thereupon theworking cycle hereinbefore described is repeated.

' 5.. The device for wrapping up the pile of rl-z'slrs in an inner andouter envelop, (Figs.

14, 6 and 1930.)This device possesses as already stated, two casingshaving the same vertical axis arranged one above another and ofsubstantially cylindrical shape. 121 denotes the upper casing and 120the lower one. These casings consist of two parts and they are attachedto vertical plates 122 and 123, which are instaggered relation one tovanother and fixed to the frame 1." (Figs. 1,

G and 20.) The casing 121 is capable of being adjusted in. the axialdirection as re-' gards the casing-120. Between the two casings-120 and121 there are provided a plurality of vertical wrapping rolls 124 (Fig.3) forming a complete ring concentric-to the axis of the two casings 120and 121.;- The axis of said rolls are supported in'the cas ings 120 and121 and they are positively connected one to another. The rolls 124 arealternately of different length. (Fig. 3) and they are provided withmembers 125adjustable in thelongitudinal direction and being sideanother and permitting to adjust the roller parts 125 into a numberofdifi'erent positions as regards the rollers 124. Owing to thisadjustable arrangement of the roller parts 125 and of the casing121,it-is possible to' alter the operative length of the wrapping rollers,so that the machine is. adapted to wrap up piles of chocolate disks ofdiffer ent heigh The axes of the rollers 124are guided in inclined slots126; (Fig. 22 of pivotally'arranged disks 127,and 12 1 mounted in aconcentric manner in the casings 120 and 121. Each pair of these axes isconnected at both ends by means of rods 128 to a fixed pin 129 igs. 19and 21), two and two of these rods being-fixed to the same pin 129.The-pins 129 are screwed into sleeves 130 and 130 (Fig; 19) the latterbeing mounted concentrically in the casings 120 and 121 and beingprevented from turning. The wrapplng rollers are positively driven bytoothed wheels; to effect this there are loosely mounted uponthe pins129 ofthe sleeves 130 small toothed wheels 131. These wheels 131 gearwith a toothed wheel 132 loosely mounted on the hereinbefore mentionedconcentric guide piece 103 of the casing 120 as well as with smalltoothed wheels 133 fixed to the roller ends projecting" into the casing120 (Figs. 19, 26 and 28).. One of the toothed wheels 131 gears with atoothed wheel 134 carrying a smaller toothed wheel 135 and mounted on avertical shaft 136 supported by the casing 120. The toothed wheel 135gears with the beforementioned toothed wheel. 37, which receives itsmotion "from the shaft 33 and which actuates intermittingly the wrappingrollers. (Figs. 3,19 and 26.) In the sides of the two sleeves 130 and130 facing one another'there are provided radial guides 137, in whichare guided "folding! members 138 (Figs. 24::1-nd 25). These foldingmembers are capable of being simultaneously moved in. the guides 137inwardor. outwards For this; reason each of-said members 138 carries pin139 and between sleeves 130 and; 1 .30" and the casing 1215,,respectively the casing 120 there are pivotally mounted ringsa14'0 and140., respectively, (Figs. 19

and-12d). Each of these rings 140, 140 is provided with a flangeprojecting beyond the inner side of the sleeve-130 and 130 respectively,and having inclined slots. 141

- mag. 26-), intowhich project" the pins 139 of? the folding members 138((Fig. 19). The

disks127 and 127 which permit the adjustmenti of the rollers 124 axiallyby means of the slots 126, are rovided with arms 142 and' 142 respectivey, (Figs. 3, 9 and 20) connected together by means of a pin 143. Thispin carries a roll, while a tension spring 144 (Fig. 20) pressessaidroll with the pin against a cam disk 145 attached to the feed wheel38 (Figs. 3 and 6). The rings 140' and 140 permitting a radialadjustment of the folding members 138 by means of the slots 141 areconnected together by means of a pin 146 (Figs. 3, 6 and 20). The lowerring 140 carries a toothed segment 147, engaged by a second segment 148pivotally mounted on the axis.

136 and connected to an arm 149, which lies with a roller within reachof a cam disk 150 rotating with the wheel 38 (Figs. 6, 19 and 20). Atension spring 151 (Fig. 20) has the tendency to rotate the two rings140 and 140 in such a manner, that the folding members 138' are broughtinto their outer positions (Fig. 6, upper half). 151 denotes a coverprovided on the upper casing 121 (Fig. 19). v

The cam disks 145 and 150 transmit alternately an intermittent rotarymotion in the one and the other direction to the disks 147,

147 and the. rings 140, 140 If the disks the disks k and the envelo aretaken out of a magazine.

and the rings are rotated owing to the action ofthe cam disks 145 and150 upon the pin 143 and the arm'149 in the direction of the arrowsshownin Figs. 20 and 22, the rollers 124 are moved radially outward(Fig. 23) while the folding members 138 are moved inward (see lower halfof Fig. 24 1 the latter the stationary toothed wheels 131;

this is effected by the connecting rods 128.

The casing 121 and the parts 127, 130 and 131 mounted therein, areprovided with central passages sufliciently great to permit the passingtherethrough of the pile of disks er half of to be wrapped up and of thefinished chocolate roll," respectively.

' The .piled up round chocolate disks s placed between two cardboarddisks lc'are wrapped, asalready stated, inan inner envelop-152" ofcardboard. This envelop of cardboard 152; forms together with theclosing disks k a case or box, which is after-, ward wrapped up in anenvelop 153 of thin paper forming the; proper wrapping cover. (Fig.331.) The width of the envelop 153 is usually greater than that of theenvelop-152 (Fig. 31), sothat the edges of the envelop projecting beyondthe disks is are folded down against the ends of the pile, for thepurpose of being glutened to v of cardboard (Fig. 32). The two verticaly arranged envelops 152 and'153 are fed in a horizontal. direction. fromopposite sides toward the wrapping rollers 124 (Figs. 1 and 6). Toefiect this, there are provided pairs of feed rollers, which aredescribed later on. These rollers are supportedby plates 122 and 123 andthey push said envelops lying upon these plates toward the wrappingrollers 124, the arrangement being such, that one A rollerv of saidpairs. The envelop of cardboard is out from a coiled band, while thepaper envelops 153 having. the proper length As soon as this envelop 153has been taken out of the magazine there is applied an adhesivesubstance to three of its sides.

The wrapping device works as follows together with the hereinbeforedescribed pushand101 and the pile of disks gripped by the latter arevertically moved downward, the

wrapping rolls 124, 125 are radially moved 1 one from the other (Fig.23). The pile of mg in and out device: Before the rods 100- .rollers andthe wrapping rollers are hereenvelops and they wrap the latter round therotating pile of disks, the envelops 152 and 'velop 153 projectingbeyond the ends of 153 overlapping one another to the amount band 0,respectively, (Fig. 33) the overlapping parts of the envelop 153 beingpasted to the ends of the roll.

The pile of disks and the envelops are now in the position shown in Fig.29, in which said pileis only held in its proper position by the pins108 and l12 prejecting to a certain amount out of the rodslOO and 101;this amount isa little greater than that by which the outer envelop153-projects beyond the upper and lower edgesof the inner envelop. Thispermits the provision of sufiicient space for the folding members 138,which are now moved inward by means of the rings 140 and 140 rotated inthe proper direction for causing such a movement of said members.VVhilethe pile of disks and its envelops are further rotated,'the' edgesof the paper enthe pile, respectively beyond the disks h of cardboard,are bent inward, z. 6. they are folded upon the disk It, being thenpasted to the latter (Fig. 30). By this time the fold .ing members 138and the wrappingrollers 1.24, 125 are moved outward, stopped and thefinished chocolate rolls are introduced'by means of the rods 100 and101, pushing said rolls upward and out of the rollers 124, 125, into thereceptacle arranged above the wrapping device. The finished chocolateroll has the shape shown in Fig. 32. The hereinbefore described workingcycle is now repeated.

6. The feed mechanism for the celops (cardboard-strips) and the scissorsfor cutting these strips, (Figs. 1, 4, 5, 9, 36 and 48.) Thecardboard-strips arecut from a. band, which is coiled upon an axis 154.

This vertical shaft arranged below the table 66 is pivotally supportedby the arm .65 of A the machine frame 1 and it carries a belt.

roller 155 (Fig. 9), which is connected by means of a belt156 to an axis157 also vertically supported in the machine frame 1 (Figs. 1 and 4). Onthis axis 157 is mounted a roll 158. working together with anintermediate roll 159 ,to guide the band of cardboard passing betweenthetwo rolls 158 and 159 (Figs. 1, 4 and 6). The two rolls are connectedby means of toothed wheels 160 one to another and to a chain-wheel 161(Fig. 1), which is connected by means of a chain 162 to the hereinbeforementioned inner en chain-wheel so. This wheel so, and thetoothedwheel29, connected therewith transmits to the two rollers 158 and .159 anintermittent rotary motion in such a direction, that they exert a pullupon the carboardstrip. Near the two rollers 158 and 159 there arearranged thescissors for cutting the cardboardstrips 1'52'from acard-board band. These scissors consist of the blade 163 (Fig. 6)attached to the plate 123 and of the blade 164 pivotally connected tothe same plate 123. This blade 164 carries a toothed segment 165,engaging a secondtoothed segment 166. (Fig. 48.) The latter is connectedby means of an axis supported by the frame 1. to a lever 167, which isbrought together with a roll within reach of lifting-cam 20 of the camdrum 19 (Fig. 5).

To effect this, there is. provided a tension spring 168 connected tothesegment 166. A-

pressure arm 169 works together with the scissors 163,164, said arm 169being loosely mounted upon the shaft of the scissors blade 1.64 while apin 170 of said arm acted upon by a tension-spring 171 is pressed fromoutside against the blade 164 (Fig. 48). This pressure armholds thecarboard-band in its proper position, when the strip is cut ofl. Betweenthe rollers 158,159 and the wrapping rollers, there are arranged upperand lower guiding rails 172 (Figs. 1, 6 and 48) connected to the plate123 and guiding the band and the vertically arranged cut off strip in ahorizontal direction.

Theabove described device is further provided. witha pair of, verticalfeed rollers 173, 174 for the cut ofl" strip of cardboard. The innerr'0ller173 is fixedto the plate 123, while the outer roller 174'iscapable of being shifted in inclinedslots 175 of bearings 176 (Figs.1, 6 and 36) fixed to the plate 123; this roller 174 is also pressed bymeans of a tension spring 177 against the inner roller 173. Toadjust theroller 174 there are provided twolevers 17 9 fixed to a vertical shaft178 The; beveledends of these levers-179 are pressed by means of tensionsprings 180 against the end'sof'the axis of the roller 174, so thatthelatte'r is liftedofl the roller 173 (Fig. 36). The. axis 178 carriesan arm 181,

which is within reach of a segment 165 of the scissors (Figs. 36and 48).An intermittent rotary motion is transmitted by means of a belt 183(Figs. 4 and'6) from a rope pulley 182 (Figs. 3 and 19) mounted onto acountershaft 136 to the roller. 174.

The card-board-strip is cut oil" when the rollers 158,159 remainstationary, the band being then held in its proper position by means ofthe pressure arm 169; the roller 174 is at this time also disengaged andit remains stationary. When the lifting cam 20 of the drum 19 strikesagainst the lever 167, the scissors 163, 164 are closed and the strip iscut off and by the time that the scis-
